How do i reserve an ip address on my LAN so dhcp cannot assign it
It all depends on the brand of your router, but mainly is to jump into the GUI with your admin password, look for DHCP options, static DHCP and save the MAC Address of the host with the desired IP.
SOURCE: Router doesn't obtain WAN IP address (DHCP)
you can hook the router up and go into the settings by when it is hooked up to your computer, type in http://192.168.0.1 and the password is usually user or admin. the password is usually password, unless it was changed. you may be able to change settings to fix this problem through that GUI

I think the screen you may be looking at is the Application layer forwarding screen, the drop down box being populated by DHCP clients, that's why it isn't seeing the DVR. The DMZ Hosting screen doesn't have a drop down box, it only requires an IP address to be entered.
Hope this helps!

Plug the second router into the lan not the wan and it will act as a switch instead of a router
SOURCE: 3CRWER100-75 no DHCP IP on child routers
router 1 (base) router 2 (repeater) router 1 (base) is the network, the SSID is where u get your internet connection set router 2 with same SSID, DHCP on. i advise connecting hardline to make sure both routers are working correctly. once thats verified then go wifi
SOURCE: TRENDnet TEW-432BRP router cannot obtain IP through DHCP
it seems that ur PC & cable modem configuration is ok, now the problem is with ur router WAN interface configuration. the problem would be one out of 2 - first to check whether ur router wan interface is configured properly to obtain IP address from DHCP (if possible, u can give the static ip address with same series as cable modem) second to check with ur ISP.
An IP
address conflict occurs
when two computers on a LAN or the Internet have been assigned the same IP. IP
conflicts between two computers normally render either one or both of them
unusable for network operations.
How IP
Address Conflicts Happen
Two
computers can acquire conflicting IP addresses in any of several ways:
· A system administrator assigns two
computers on the LAN the same Static IP Address.
· A system administrator assigns a
computer a static IP address within the local network's DHCP range (dynamic IP
range), and the same address is automatically assigned by the LAN DHCP
server.
· A malfunction in the network's DHCP
server allows the same dynamic address to automatically be assigned to multiple
computers.
· An ISP accidentally assigns two
customers the same IP address (either statically or dynamically).
· A mobile computer is put into standby
/ hibernate mode and then awakened later.
Note that
other forms of IP conflicts can also occur on a network. For example, one computer
may experience an IP address conflict with itself if that computer is
configured with multiple Network Adapters. System administrators may also
create IP conflicts by accidentally connecting two ports of a network switch or
router to each other.
Recognizing
IP Address Conflicts
On most
Microsoft Windows computers, if you attempt to set a fixed (static) IP address
that is already active on the local network, you will receive the following
pop-up error message:
The static IP address that was just configured is already in use on the
network. Please reconfigure a different IP address.
On newer
Microsoft Windows computers having dynamic IP conflicts, you should receive a
balloon error message in the Taskbar as soon as the operating system detects
the issue:
There is an IP address conflict with another system on the network.
Sometimes,
especially on older Windows computers, a message similar to the following may
instead appear in a pop-up window:
The system has detected a conflict for IP address...
On Mac or
Linux computers, a similar message will normally appear on screen.
Resolving IP
Address Conflicts
Try the
following remedies for IP conflicts:
1. For
networks where IP addresses are fixed (statically assigned), ensure each local
host is configured with a
unique IP address.
2. If your
computer has a dynamically assigned address, releasing
and renewing its IP address can
workaround IP address conflicts.
3. If your home router is believed to have a
faulty DHCP server causing IP conflicts on the home network, upgrading the
router firmware may resolve this problem.
Step 1:
Access the router's web-based setup page. For instructions, click here.
NOTE: To learn how to access the web-based setup page on a Mac computer, click here.
Step 2:
Click Setup > Basic Setup.
Step 3:
Make sure that the DHCP Server option is Enabled. Click the DHCP Reservation button if you want to assign a fixed local IP address to a MAC address.
Step 4:
When you click on DHCP Reservation, a new web browser window will pop-up. Click the Select checkbox to reserve a client's IP address. Click the Add Clients button afterwards.
Step 5:
If you want to manually assign an IP address, enter the client's host name in the Enter Client Name field. You can do this as well in the IP Address and MAC address fields.
Step 6:
Click the Add button.
Step 7:
A list of DHCP clients and their fixed local IP
addresses will be displayed at the bottom of the screen. If you want to
remove a client from this list, click the Remove button.
